Mounting system for window treatment

ABSTRACT

An adjustable mounting system for use with a variety of window treatments comprises a head rail, an adjustable support rod, and one or more clips for coupling the support rod to the head rail. The mounting system is preferably non-invasive and does not damage window casings. The mounting system may be installed very quickly and easily, without the need for any tools. The head rail is adapted for use with a wide variety of window treatment assemblies.

BACKGROUND

1. Field of the Invention

The present invention relates to mounting systems for window treatments.

2. Description of Related Art

Most systems for mounting window treatments include at least two brackets that are configured to receive a head rail of a window treatment. The brackets are fastened to the window casing or the wall in front of the window casing with screws, bolts, or nails, so that the brackets can support the head rail of the window treatment. This leaves holes and damage in the window casing or wall that must be repaired if the window treatment is replaced. On small window casings, such as those having a width of about four feet or less, only two brackets, one mounted adjacent each side of the window casing, are used. This often results in the middle portion of the head rail sagging over time. On larger windows, center brackets must be used to support the load of the head rail and window treatment.

Another disadvantage of these conventional mounting systems is that they can be very difficult and time consuming for an average consumer to install. For installations in which the brackets are screwed to the wall in front of the window frame, the widths of the brackets have to be measured, the brackets must be properly leveled, and pilot holes must be made, before the brackets can be mounted. This requires that the installer have certain tools and skills. Further, the installation of the brackets can cause permanent damage to the window casing or the wall to which they are mounted.

Some mounting systems do not require screw-mounted brackets. These non-intrusive mounting systems often use a supplemental cap or mounting bracket for one or both ends of the head rail. These independently functioning brackets are commonly spring-loaded or use a lever and cam system to generate compression. However, these supplemental caps have several disadvantages, as well. In particular, the compression that is achieved is often only great enough to support shear-type drapes and very light-weight curtains. Such brackets do not generate enough strength to support heavy rolling shades, mini-blinds, or drapes. In particular, after the window treatment has been opened and closed repeatedly, these types of brackets, much like conventional screw-in brackets, often must rely upon the strength and integrity of the head rail itself to support the window treatment. This often results in the middle portion of the head rail sagging over time.

Although great strides have been made in the area of mounting systems for window treatments, many shortcomings remain.

DETAILED DESCRIPTION

Referring to FIG. 1 in the drawings, a rear view of the preferred embodiment of a mounting system 100 for a window treatment is illustrated. Mounting system 100 comprises a head rail 102, an adjustable support rod 104, and at least one clip member 106. In the preferred embodiment, clip members 106 releasably grip support rod 104, so as to couple head rail 102 to support rod 104. Mounting system 100 is configured and adapted to support a wide variety of window treatments, such as window treatments 610, 620, 630, 640, and 650 depicted in FIGS. 6A-6E. As explained more fully herein, window treatments 610, 620, 630, 640, and 650 may be integral with head rail 102, or may be coupled to or carried by head rail 102 according to a wide variety of means.

Support rod 104 comprises a tubular rod portion 110, a guide cutout 112, a sliding guide 114 that protrudes into guide cutout 112, an adjustment shaft 116, an adjustment collar 118, and end caps 120 a and 120 b. End caps 120 a and 120 b comprise coupling portions 121 a and 121 b and pad portions 123 a and 123 b, respectively. Support rod 104 has an adjustable length and is configured to be installed into a window casing 226 (see FIGS. 2A-2C) by a press-fit attachment. Although support rod 104 is depicted as having a round cross-sectional shape, in alternate embodiments, support rod 104 may be comprised of a variety of shapes, including, but not limited to, oval, elliptical, square, rectangular, triangular, hexagonal, and so forth. In addition, although support rod 104 is depicted as a rigid rod, it will be appreciated that in another embodiment, support rod 104 comprises a multi-piece, telescoping, spring-loaded compression rod. Sliding guide 114 is coupled to adjustment shaft 116 and slidingly fits within guide cutout 112. In this manner, the length of guide cutout 112 determines the overall adjustment length of mounting system 100. Because sliding guide 114 protrudes into guide cutout 112, adjustment shaft 116 is prevented from rotating relative to support rod 104.

Adjustment collar 118 preferably comprises a finger tightening portion 125 and an integral wrench tightening portion 127. Finger tightening portion 125 preferably includes gripping means that allow a user to get a firm hand or finger grip on adjustment collar 118. For example, in FIG. 1, finger tightening portion 125 comprises upraised ridges. It will be appreciated that other gripping means may be utilized with finger tightening portion 125, such as upraised ridges, knurls, slots, and notches, and that the gripping means may be either integral with finger tightening portion 125 or may be a separate component, such as a non-slip film or grip tape. Wrench tightening portion 127 preferably has a hexagonal cross-sectional shape, so that a conventional hexagonal wrench may be used to tighten, loosen, and otherwise adjust adjustment collar 118. Although support rod 104 is configured such that sufficient torque may be imparted to adjustment collar 118 by simple hand tightening, wrench tightening portion 127 provides a means for users who may not be able to generate sufficient hand strength, such as elderly users or users with disabilities, to adjust adjustment collar 118.

Adjustment collar 118 is operably coupled to adjustment shaft 116. Although adjustment shaft 116 is free to translate axially according to the length of guide cutout 112, adjustment collar 118 restricts the movement of adjustment shaft 116 relative to support rod 104 by butting up against an end 119 of support rod 104. In this manner, rotation of adjustment collar 118 in the appropriate direction relative to adjustment shaft 116, causes adjustment shaft 118 and end cap 120 b to translate outward away from support rod 104 and into contact with window casing 226, thereby forming a press-fit of mounting system 100 into window casing 226. Although mounting system 100 has been shown with a threaded coupling as a means for adjustment, it should be understood that other means for adjustment, such as ratchet systems and clamping systems may be utilized.

In the preferred embodiment, the length of head rail 102 matches the distance between the walls of window casing 226. This allows head rail 102 to conceal end caps 120 a and 120 b after installation. It should be understood that in some applications it may be necessary or desirable to trim head rail 102 to fit appropriately within window casing 226. The length of support rod 104 may also be trimmed, particularly from the end adjacent end cap 120 a, to fit window casing 226.

It is preferred that the interior cross-sectional shape of head rail 102 and the exterior cross-sectional shape of at least one portion of end caps 120 a and 120 b be similar. This ensures that head rail 102 will conceal end caps 120 a and 120 b and not rotate relative to support rod 104 after installation. In the example of FIG. 1, head rail 102 has a generally square interior cross-sectional shape and pad portions 123 a and 123 b of end caps 120 a and 120 b, respectively, have square exterior cross-sectional shapes. It will be appreciated that other shapes, sizes, and configurations of head rail 102, end cap 120 a, and/or end cap 120 b may be utilized to conceal ends caps 120 a and 120 b and prevent movement of head rail 102 relative to support rod 104.

Mounting system 100 may be installed very quickly and easily, without the need for any tools. First, support rod 104 is press fit into window casing 226, a process more fully described in FIGS. 2A through 2C. Mounting system 100 is easily leveled during installation. Because support rod 104 is merely press-fit into window casing 226, mounting system 100 is non-invasive and does not damage window casing 226. Once support rod 104 is secured within window casing 226, head rail 102 is simply snapped onto support rod 104 via clip members 106. This allows head rail 102 to be quickly and easily removed from support rod 104, while allowing support rod 104 to remain in place in window casing 226. It will be appreciated that support rod 104 may also be quickly and easily removed and reinstalled without damaging window casing 226.

Another advantage of mounting system 100 is that the weight of head rail 102 and any associated window treatment can be more evenly distributed along support rod 104, thus preventing sagging. Clip members 106 serve to transfer and distribute loads from head rail 102, and any window treatment associated with head rail 102, through support rod 104 to window casing 226. Although only two clip members 106 are shown in FIG. 1, it will be appreciated that any number of clip members 106 may be utilized, depending upon the load to be distributed.

Referring now to FIGS. 2A-2C in the drawings, the process of installing mounting system 100 in window casing 226 is illustrated. First, adjustment collar 118 is loosened, i.e., rotated in one of the directions indicated by arrow 240, to allow adjustment shaft 116 to advance into the interior portion of tubular rod portion 110. This provides clearance for support rod 104 to be inserted between the sides of window casing 226. The distance that adjustment shaft 116 may be recessed into or extended out from tubular rod portion 110 is limited by the length of guide cutout 112. Once the length of support rod 104 has been adjusted to allow adequate clearance between window casings 226, adjustment collar 118 is seated against end 119 of tubular rod portion 110. Then, end cap 120 a is placed into contact with one side of window casing 226. These steps are shown in FIG. 2B.

Next, adjustment collar 118 is tightened, i.e., rotated in one of the directions indicated by arrow 240, to force adjustment shaft 116 in the direction of arrow 235. This causes end cap 120 b to be advanced toward window casing 226. End cap 120 b is advanced in this manner until end cap 120 a makes contact with window casing 226. As explained in more detail herein, end caps 120 a and 120 b may comprise compliant material or other means for positively engaging window casing 226. Thus, additional torque may be imparted upon adjustment collar 118 after the initial contact between end cap 120 a and window casing 226. This ensures a firm press fit between support rod 104 and window casing 226. Support rod 104 may include means for preventing adjustment collar from loosening once tightened to the desired position. For example, a tension nut or retaining clip may be added to ensure that adjustment collar does not inadvertently loosen once tightened.

Referring now to FIG. 3 in the drawings, the preferred embodiment of clip member 106 is illustrated. Clip member 106 comprises a back portion 330, a top portion 332, a bottom portion 334, a left side portion 336, and a right side portion 338. Top and bottom portions 332 and 334 extend forward from back portion 330, and connect left and right side portions 336 and 338. Left side portion 336 comprises left top wing portion 340 and left bottom wing portion 342. Likewise, right side portion 338 comprises a right top wing portion 344 and a right bottom wing portion 346. Left top wing portion 340 and left bottom wing portion 342 each comprise a gripping portion 348 and 350, respectively. In a similar fashion, right top wing potion 344 and right bottom wing portion 346 each comprise a gripping portion 352 and 354, respectively. Gripping portions 348, 350, 352, and 354 are shaped, formed, and configured to releasably grip and retain support rod 104. In the preferred embodiment, gripping portions 348, 350, 352, and 354 are smooth curves that are separated by a distance that is shorter than the diameter of support rod 104. This allows support rod 104 to be snapped into place in the void spaces formed by left and right side portions 336 and 338 and by gripping portions 348, 350, 352, and 354. Although right and left side portions 336 and 338 have been depicted in the exemplary embodiment as being shaped to generally grasp and retain a round shaped rod, in other alternative embodiments, right and left side portions 336 and 338 may be adapted to grip and retain rods of other shapes, including but not limited to, oval, elliptical, square, rectangular, triangular, hexagonal, and so forth. However, it should be understood that gripping portions 348, 350, 352, and 354 may have other shapes, sizes and dimensions, and may comprise other means for releasably retaining support rod 104.

Clip member 106 is preferably made of any appropriate material, including but not limited to, plastic, metal, rubber, nylon, and others. However, clip member 106 may be varied in many ways, including size and shape, depending upon the particular implementation desired. In some alternative embodiments back portion 330 may not be present. In other alternative embodiments, top and/or bottom portions 332 and 334 may be missing or may extend to a greater or lesser extent from a back portion 330.

It is preferred that clip member 106 be securely fastened to head rail 102 at selected locations. This can be achieved by snapping clip member 106 into the interior portion of head rail 102, by press-fitting clip member 106 into the interior portion of head rail 102, by sliding clip member 106 into the interior portion of head rail 102, or other suitable means. In an alternative embodiment, clip member 106 is integrally formed with head rail 102. In another alternative embodiment, clip member 106 may be adjustably relocated along the length of head rail 102 by sliding clip member 106 within the channel formed by head rail 102.

It will be appreciated that clip member 106 may perform other functions in addition to releasably retaining head rail 102 to support rod 104. For example, clip member 106 may contain one or more string guides, apertures, notches, or slots, such as notches 360 and 362, to accommodate strings, cables, and other operating controls used to operate various window treatments associated with head rail 102.

Referring now to FIG. 4 in the drawings, a cross-sectional view of mounting bracket 100 taken at IV-IV of FIG. 1 is illustrated. Notch 360 allows a string 450 of a widow treatment to pass through clip member 106. Notch 360 is optional and may not be needed depending on the particular implementation being contemplated and the particular window treatment being used. As is shown, head rail 102 may include tabs 347 and 349 that allow head rail 102 to snap onto and grip clip members 106 and end caps 120 a and 120 b. Tabs 347 and 349 further prevent head rail 102 from moving relative to support rod 104 and window casing 226.

Referring now to FIGS. 5A-5E in the drawings, the preferred embodiment and various alternative embodiments for pad portions 123 a and 123 b are illustrated. In the preferred embodiment, pad portions 123 a and 123 b are made of the same material and have the same size and shape; however, it will be appreciated that pad portions 123 a and 123 b may be made of different materials and/or have different sizes and shapes. For simplicity, only pad portion 123 a will be shown and described in FIGS. 5A-5E. In the preferred embodiment, which is depicted in FIG. 1 and FIG. 5A, pad portion 123 a comprises a square shape, which prevents rotation of head rail 102 relative to support rod 104, and which, when abutted against the upper sides of the window casing 226, helps to prevent support rod 104 from rotating relative to window casing 226. As shown in FIG. 5A, pad portion 123 a has a flat, smooth surface 160.

In FIG. 5B, pad portion 123 a is a multi-layer pad having a first layer 562 and at least one other layer, such as a top layer 564. Top layer 564 is shown having a flat, smooth surface 566. Layers 562 and 564 may be of the same material or may be of differing materials. For example, top layer 566 may form an adhesive-type surface. For those embodiments in which top layer 564 is an adhesive layer, a release liner (not shown) may also be used to protect the adhesive until installation. In FIG. 5C, pad portion 123 a comprises raised grooves 567. It will be appreciated that raised grooves 567 may be arranged in a wide variety of patterns and shapes, including multi-directional patterns, overlapping patterns, and checkerboard patterns. In FIG. 5D, pad portion 123 a comprises a knurled surface 168. The sizes of the individual knurls may vary depending upon whether it is desired that the knurls pierce the surface of window casing 226. In FIG. 5E, pad portion 123 a comprises a wavy surface 168. Although a generally square shape has been utilized in FIGS. 5A-5E, it will be appreciated that other geometric shapes, including but not limited to, oval, elliptical, circular, rectangular, triangular, hexagonal, and so forth, may be used instead or in combination. In addition, in an alternative embodiment, end caps 120 a and 120 b may be configured to allow for the use of nails, screws, clamps, or other suitable fasteners, to aid in securing end caps 120 a and 120 b to window casing 226.

Mounting system 100 is capable of use with a wide variety of different types of window treatments, including but not limited to, Venetian blinds, rolling shades, vertical blinds, mini-blinds, curtains, drapes, and so forth. In addition, mounting system 100 allows these different types of window treatments to be quickly and easily interchanged among each other. Further, an optional valence (not shown) may be coupled to head rail 102. Utilization of an appropriately shaped, sized, and trimmed valence also allows potential gaps between head rail 102 and window casing 226 to be concealed.

Referring now to FIGS. 6A-6E in the drawings, mounting system 100 is illustrated with some exemplary types of window treatments. The window treatments in FIGS. 6A-6E, as well as other types of window treatments, may be coupled to head rail 102 as separate components, or may be integral with head rail 102.
